RN104 Remove inactive volumes Disk 3,4
Hi everyone, one of my 4 2TB drives (#2) failed in my RN104. I went ahead and bought a replacement, but after insertion it looks like i get the "remove inactive volumes disk 3,4"; with some of my dr...

So both sdc and sdd are detected as failed. Unfortunately not a good sign. It'd have been better if one of the disks was just out of sync.
I'm not sure if either of these is disk 1, you might want to double-check that by looking at disk-info.log.

I guess my main question now is: is there still a way i can force a rebuild / should i try to remove/readd the faulty disk ?
With single redundancy, you need three working disks to rebuild the fourth. You don't have that.
If the disks can be read at all, you could try cloning one or both. That might help with recovery.
RAID recovery software like ReclaiMe might be able to recover some data from the two remaining disks - not sure. You can download it and see before you pay for it. You would need a way to connect the disks to a PC (directly with SATA, or using a USB adapter/dock).

It could be that dirve #1 is not in a good state either (many ATA errors), but i guess i first have to try and force a rebuild of sorts. It was setup in RAID 5 (which still shows up in green here).
Two drive failures would cause the volume to fail.
Download the full log zip file, there is a lot more information in there than you will see in the web ui.
I did download it - what should I be looking for ?
Drive.log confirmed disk1 as ATA error prone - while still deemed alive.
Disk2 went from online to failed last week - I replaced it this morning.
Happy to post/ dig further - just let me know what to look for.
Many thanks
